Research on the Precision Testing Method of Platinum Resistance Temperature Sensor
As a kind of high precision temperature sensor,platinum resistance temperature sensor is often used in industrial production and manufacturing fields to monitor the temperature of products. Due to the particularity of platinum resistance sensor in probe position and sensor position,different precision inspection methods of platinum resistance temperature sensor have great influence on the precision test result of platinum resistance. Aiming at the above problems,a precision measurement method of platinum resistance temperature sensor is designed. Firstly,the operating environment inside the thermostatic chamber is analyzed,and the influence of the insertion depth of the sensor precision test on the precision test results is evaluated. Then,the precision test equipment and test method of platinum resistance temperature sensor are designed,and the data collection and comparison demonstration in the precision test process are realized. Finally,the precision test is carried out,and the effectiveness of the proposed precision test method is verified.
